Key specs explained for you
113,000 BTU/hr
This heating capacity determines how much energy the burner uses to warm water. Higher BTU ratings generally allow for faster heating and better performance when multiple fixtures run at once. You should compare this figure against your local climate and desired temperature rise. In colder regions, a higher BTU unit helps maintain consistent hot water flow during winter months.
5 GPM
Gallons per minute measures the maximum flow rate of hot water the unit can deliver. A 5 GPM output suits a typical single-family home with one or two bathrooms running simultaneously. If you need to run a shower and a kitchen sink at the same time, this flow rate is usually sufficient. Larger homes with multiple bathrooms may require a higher GPM model.
Propane
This fuel type indicates the heater uses liquid propane gas rather than natural gas. Propane is stored in tanks, making it suitable for homes without access to a natural gas line. You must ensure your propane supply is reliable and connected correctly. This option offers flexibility for rural or off-grid installations where piped gas is unavailable.
120 V
The voltage requirement shows the electrical power needed for the unit’s internal components. This 120-volt rating powers the digital display, safety sensors, and exhaust fan. It allows connection to standard household outlets, simplifying installation compared to units requiring 240-volt circuits. You still need a dedicated circuit for safe operation, but no specialized high-voltage wiring is necessary.
Indoor
This designation means the unit is designed for installation inside your home. It requires proper ventilation and connection to an exhaust venting system to remove combustion gases safely. Indoor models often have different safety features and dimensions than outdoor units. You must follow local building codes regarding clearances and venting to ensure safe and compliant operation within your living space.
Design and Build Quality
The GASLAND Gasmart C measures 15.6 x 9.6 x 9.6 inches and weighs a modest amount for its class. Its compact footprint allows it to mount easily on most interior walls. The unit is finished in black, which helps it blend into utility spaces without drawing attention. According to the listing, the primary heat exchanger is constructed from oxygen-free copper. This material choice offers better heat transfer efficiency compared to stainless steel alternatives. It also provides greater resilience against corrosion, which supports long-term reliability in humid environments.
Controls are centralized on an LED digital display screen. This interface lets you adjust and view the output water temperature directly. Bright indicator lights show water flow, fan operation, and flame detection status. Advanced error codes appear on the screen to help you diagnose issues quickly. The unit includes a 110/120-volt UL listed 5 feet power cord that powers the internal exhaust fan. This design ensures proper ventilation for indoor installation.
Water connections use standard 1/2" NPT fittings for incoming and outgoing lines. This compatibility simplifies plumbing work for most single-family homes. A 3-inch diameter exhaust pipe is required for safe operation. The unit also features built-in freeze protection that activates when water temperature drops below 41°F. You must keep power on for this feature to function. The DC variable frequency fan helps withstand high winds, reducing the risk of backflow or flameout in extreme weather conditions.
Setup and Everyday Use
Setting up this unit requires a licensed professional to connect it to your existing plumbing and gas lines. The water connections use standard 1/2 inch NPT fittings, which fits most common residential pipes. You must install a 3-inch diameter exhaust pipe for proper ventilation. The heater is designed for indoor use only and must be placed in a well-ventilated area. Installation is not recommended for locations above 2,000 feet above sea level. You need to ensure the area meets local building and plumbing codes.
Daily operation is managed through the LED digital display. This screen shows the output water temperature, allowing you to adjust settings precisely. The unit runs on 120 V power, which is supplied by a 5-foot UL listed power cord. This electricity powers the internal exhaust fan and the display. Indicator lights on the panel show water flow, fan status, and flame detection. If an issue arises, the advanced error code technology helps you diagnose the problem quickly.
The system includes built-in freeze protection. When water temperature drops below 41°F, the heater starts warming the water to prevent damage, provided the power remains on. It also features an overheat cutoff fuse and thermistors to monitor inlet and outlet temperatures. The DC variable frequency fan helps prevent backflow and flameout during high winds. The oxygen-free copper heat exchanger transfers heat efficiently, supporting the up to 5 GPM flow rate at 113,000 BTU/hr capacity.
Before You Buy This Unit
This unit requires a 120 V power source for its internal fan and control board. You must connect it to standard 1/2 inch NPT plumbing fittings. A 3-inch diameter exhaust pipe is mandatory for safe venting. The device is designed for indoor installation only. You cannot use it above 2,000 feet of altitude without modification. Propane is the required fuel type. You need a licensed professional for installation to meet local building codes.
